Toll roads are rare in the United Kingdom, though there are many toll bridges such as the Severn crossing. Road traffic congestion has been identified as a key concern for the future prosperity of the United Kingdom, and policies and measures are being investigated and developed by the government to ameliorate its effects.[7] In 2003, the United Kingdom's first toll motorway, the M6 Toll, opened in the West Midlands area to relieve the congested M6 motorway.[19] Rod Eddington, in his 2006 Transport’s role in sustaining the UK’s productivity and competitiveness report, recommended that the congestion problem should be tackled with a "sophisticated policy mix" of congestion-targeted road pricing and improving the capacity and performance of the transport network through infrastructure investment and better use of the existing network.[3][20] Congestion charging systems do operate in the cities of London[21] and Durham[22] and on the Dartford Crossing. In 2005, the Government published proposals for a United Kingdom-wide road pricing scheme. This was designed to be revenue neutral with other motoring taxes to be reduced to compensate.[23] The plans have been extremely controversial with 1.8 million people signing a petition against them.[24]
